Distillation Process Analyzer DPA-4.5
Installation and preparation for commissioning
Main switch and integration in an
emergency off concept required
The device has neither its own main switch nor its own emergency
off device.
For this reason, before commissioning the device:
•
Install a main switch which disconnects all poles from the
current supply.
•
Install an emergency off device for the device. If the device is
operated as part of a system, integrate it in the safety chain of
the system control.
Main switch and integration in an
emergency off concept required
When installing, make sure that:
−
The main switch and the emergency off device can be secured
against being switched on again.
−
For example, it must be possible to secure the main switch with
a lock to prevent it from being switched on without
authorization.
−
The emergency off device must be connected in such a way
that once the power supply or the activation of the power
supply has been interrupted, no situations can arise that
endanger persons or property.
−
Install the main switch and emergency off device in an easily
accessible location close to the device.
−
Label the main switch and emergency off device so that they
can be clearly associated with the device.
Preparation
WARNING
Danger of explosion due to open sources of
ignition
Operating equipment which is not an integral part
of the device and which is supplied with electricity
from the box must have its own ignition protection.
All capacities and inductivities of this operating
equipment must lie below the limit values specified
in the standards and regulations applicable to
explosion protection.
1.
Provide the energy supply lines to the device with fuses
corresponding to the specifications in the technical data.
2.
Data important for the installation can be found in the
supplied electrical engineering documentation and the
terminal diagram.
3.
Before beginning work, make sure that the system voltage
available corresponds to the operating voltage specified on
the type plate.
4.
Only use shielded cables for signal lines.
5.
Check the polarity of the signal cables.
